ILOM IP addresses are assigned to Exalogic machine components at the time of manufacturing. For a list of default ILOM IP addresses, see Default IP Addresses and Ports.
However, you can reconfigure the IP addresses by using the Oracle Exalogic Configuration Utility. The Oracle Exalogic Configuration Utility and its associated scripts reconfigure ILOM IP addresses based on the input you provide to the Exalogic Configurator spreadsheet.
If the Exalogic Configuration Utility fails to reconfigure IP addresses or misconfigures IP addresses, you can configure IP addresses manually, as described in Configure ILOM IP Addresses Manually.
